To all whom it may concern:

Be it known that I, ELLIS IV. COOPER, a

citizen of the United States, residing at as, for instance, magazines, during thegreater part of the time the product will be of a common variety which canstand handling, but at times in such printing it is desirable to produce a product of higher grade which should be handled during the delivery operation as little as possible. When work of the ordinary variety is being produced, the delivery may be and preferably is a continuous one, but when a higher grade product is being produced, to avoid handling the product is delivered in bunches, each bunch having a predetermined number of the products. In this latter or bunch delivery the products are delivered generally to a traveling carrier having a series of partitions or pockets the carrier being operated intermittently to move forward a pocket length when a pocket has received a predetermined number of products.

It is an object of the invention to produce a delivery which may be operated either to deliver the products, as printed sheets, continuously, or to deliver such products in bunches or bundles having a predetermined number.

It is a further object of the invention to provide a carrier of improved construction which may be employed either for the continuous delivery or bunch delivery, as desired.

For a full understanding ofthe invention, a detailed description of mechanism embodying the same will now be given in connection with the accompanying drawings, in which Figure l is a eirleelevation, partly. sew

tion, with certain parts broken away to show the construction of a part of the im proved delivery mechanism, the part shown being adapted to deliver the products in bunches, each bunch having a predetermined number. Fig. 2 is a side elevation, partly in section and partly broken away, of a portion of the improved delivery, the part shown being arranged for delivering the product continuously, the view being taken on the side of the machine opposite to that shown in Fig. 1; Fig. 3 is a plan view of the improved delivery, device, showing the construction illustrated in Figs. 1 and 2;

Figs. 4, 5 and 6 are detail views on an envention maybe used in other relations, and

that products from other sources than the delivery cylinder of a printing machine may be delivered by the improved mechanism. This delivery cylinder is of any usual or suitable construction and has cooperating therewith the usual stripper 2.

In accordance with the invention, a delivery mechanism is provided whereby the products may be delivered from the delivery cylinder either in bunches, each bunch having a certain predetermined number, or continuously. The particular mechanism for efl'ecting this maybe widely varied. In the best constructions, and as illustrated, the delivery will include a traveling carrier with mechanism for driving this car- 'rienintermittently or continuously, as desired, the carrier being so constructed as to permit the products to be taken thereby either in bunches or continuously. The particular construction of this carrier may vary widely. As illustrated, it includes a plurality of endless tapes 3. These tapes are supported in any suitable manner. In

the particular construction illustrated, the

tapes are carried on cross-bars or rods 4, these rods being secured to a pair of chains 5 which are driven in any suitable manner, as by sprockets 6, 7 carried respectively on 'crcaashafta 8, 9 suitably journuled in the frame of the machine. Additional supportslOmay be provided if desired to prevent the bars and tapes from sagging, these supports being in the form of bars which are supported by suitablebraces 11 on the frame of the machine, and a further center support 13 may be provided, if desired.

In order that the carrier may operate to deliver the "products in bunches, each bunch having a predetermined number, the carrler is provided with instrumentahties forming recesses or pockets into which the products are delivered from the delivery cylinder, the carrier being intermittently moved ahead a pocket length by mechanism hereinafter described, when the desired number of products have been delivered to a pocket. The particular means employed for forming thejpockets may be varied, but

these means will be of such character that they can be withdrawn from the path of the sheets as they. are delivered from the delivery-cylinder, when it is desired to operate thecarrier to deliver products continuously.

In the construction illustrated, these pockets .areformed by providing pins or fingers 14 suitably secured to the carrier, these fingers .being spaced apart longitudinally of the carrier asuflicientdistance to form pockets of the required dimensions. When these pocket forming devices are pins or fingers they g-ai-e preferably carried on the rods 4:, before referred to, which are mounted so as to be rotatable in suitable bearings so that the rods may be turned to cause the pins to assume a position parallel'with and below r the run of the tapes, as shown in Fig. 5,

' tiuously.

when it'is desired tooperate the carrier con- The particular constructlon for mounting therodsmay be var1ed,'but as shown each rod is provided with collars 15, .16 located beyond or outsidethe tapes, be-

7' brackets22. the rods being rotatable in the brackets. Throi-igh the tension of. the spring the rod is held firmly inathe bearing 21 with the pin in upright position, when the nose 18 is in engagement with the. notch 19.

'VVhen it is desired to have the pins turned down out of the path of the product, the p n is grasped and-pulled outwardly, or to the left, as shown in Fig. 4, which causes the nose 18 to become disengaged from the notch 19 with whichit was 1n engagement.

Thepin is then turned down, the rod rotatangm its bearings until the nose 18 engages with the notch 20, the pin then being in the position shown in Fig. 5 and out of the way of the product as they are delivered 'onto the tapes, and the pins are held firmly in such position.

In accordance with the invention, connectionsare provided for driving the carrier either intermittently, to deliver the product in bunches, or substantially continuously, to effect a continuous delivery of the product.

Referring first to the means employed for effecting an intermittent or periodic movement of the carrier, these means will be preferably such as to give the carrier, when it is moved, a very quick movement, or jump, so that the carrier will be moved a pocket length with sullicient speed, after a pocket has been filled, to permit that pocket to be moved out of the way and the next pocket moved into position in time to catch the neXt product delivered from the delivery cylinder. The means for moving the car- .rier will also preferably, in the best constructions, form in effect a counting means,

these means operating to move the carrier after a predetermined number of products have been delivered to a pocket. While the particular construction for effecting this re sult may be varied, as illustrated there is provided a power shaft 25 which, through a train of gears 25, 26, 27, 28, drives a short shaft 29 on which there is secured an arm 30 having a pin 31. This pin is adapted to engage with recesses 32 in a recessed or star wheel 33 suitably mounted on a stud 3-1 in the frame of the machine. Fast on the stud 34 is a cam 35 (see Fig. 3) having a cam groove 36 in which is mounted to run a cam roll 37 carried on an arm 38, pivoted at 39 in a suitable bracket on the frame of the machine. The other end of this arm is provided with a cam roll 40 which works in a grooved collar 41 on a shaft 42 suitably journaled in the frame of the machine. Keyed on the shaft 12, so as to slide thereon, is a second recessed or star wheel 43 provided with recesses 44 with which is adapted to engage the pin 31 before referred to, the wheel 43 being turned by this pin. The shaft 42, which is turned by the star wheel 43, is provided with a gear 45 which is in mesh with a gear 16 slidably mounted on the chain sprocket shaft 8, before referred to.

Through the construction illustrated, the arm 38 is operated to slide the star wheel into position to be engaged by the pin 31 once for every complete revolution of the star wheel 33. and for each revolution of the star wheel 33 the star wheel 4-3 is given a quarter turn. An intermittent drive is thus provided for the carrier, the carrier being moved forward at each quarter turn of the star wheel 43a pocket distance after the pocket has had delivered to it the predeten mined number of products. This movement is further a very quick one, and permits of the proper operation of the carrier.

The means whereby the carrier may be driven continuously to effect a continuous delivery of the product will now be described. Preliminarily, it may be stated that when it is desired to operate the carrier continuously the pins or fingers 14:, before referred to, are placed in their recumbent position out of the path of the products, and the connections for driving the carrier intermittently just described are thrown out of operation, this being conveniently accomplished by making the gear 25 on the power shaft 25 a sliding gear and unmeshing it from gear 26 by sliding it along the shaft, and also unmeshing gear 46 from gear 42. The particular mechanism employed for effecting the continuous movement of the carrier may be varied somewhat in construction. As illustrated, this mechanism is positioned on the other side of the machine, and, for compactness and simplicity of operation, is operated from power shaft 25, before referred to. In the particular construction illustrated, the end of the sprocket shaft 8 on the other side of the machine is provided with a ratchet 4-8 fast on the shaft with which cotiperates a pawl 49 pivoted on a pawl arm 50 pivotally mounted on the shaft 8. This arm is operated to move the carrier substantially continuously by means of an eccentric 51 on power shaft 25 and eccentric rod 52 connected to the eccentric and the pawl arm 50. When it is desired to discontinue the means for driving the shaft just described for operating the carrier sub stantially continuously the pawl is, by means of a handle 58, lifted up out of engagement with the ratchet and the pawl arm simply runs free on the shaft.

While the invention has been shown and described as used in connection with the delivery cylinder of a printing machine, it will be understood that it may be used in other relations for delivering products from various sources of supply, and that it is not to be limited to use in conjunction with a printing machine nor to the particular construction or arrangement of the parts described, but that changes and variations may be made in the same without departing from the invention.

What is claimed is:

1. In a delivery device, the combination with a traveling carrier having sheet receiving pockets, of mechanism for giving the carrier an intermittent forward movement after a predetermined number of sheets have been deposited in a pocket, mechanism for giving the carrier a contions whereby either mechanism may be thrown into operative relation with respect .to the carrier, and means whereby the pockets on the carrier may be thrown out of sheet receiving position.
